You can start them whenever, but it is a possibility that your period will be delayed.
You can start the pill at any time during your cycle. If you start a week before your period, use a back up method of birth control for the first seven days of the pack.
Continue taking your birth control pills as scheduled.
If you start your birth control after your period, it is effective within days, if you start at any other time it should not be relied upon until after the next period. This is because ovulation may have already occurred (there is an egg already released waiting to be fertilized)
It really just depends on what type of birth control your taking, and when you start to take them. If you missed a week or two after getting off your period then you may spot for a few days, but you should start when your supposed to.
No. You need to start birth control BEFORE you have sex for it to be effective.
Yes, if you start the birth control pill for the first time before your period, your period will come later. It usually comes during the last week of the cycle.
There's no need to wait.
You are supposed to start your pills the Sunday after ur period ends. But starting a week after ur period ends isn't bad either but ur period will be a little off track
I recently just restarted birth control after a month of being off of it and was previously on it for a year, during this time I started my period every Tuesday, since restarting birth control would my period still be on a Tuesday if I was a Sunday starter?? :)
To my knowledge the last week of birth control pills are placebos. That means they are simply sugar pills that help keep you in a routine. I think the lack of regular birth control pills during that last week cause you to start your period because you stop the hormones associated with those pills. Of course, I haven't taken them for over 10 years and the new types may be different.
If you want to suppress just the one period you can get specific pills from the doctor, but if you need contraception as well you can start birth control. However you will not be protected from pregnancy for about 3 weeks.
